FIELD OF THE INVENTION

The present invention relates to collapsible containers_for mounting to independent surfaces, more particularly but not exclusively bags to mount on a seat in an auditorium or theatre for example to contain items during a performance or show.

BACKGROUND

In a number of situations people carry items for use or consumption during an event such as a meeting or performance, in which they are sitting or standing behind an item with an upright surface, such as a seat back or a barrier. During the event people want to access these items conveniently but it is often not desirable to carry them throughout the event or to place them on the floor.

For example, in cinemas there is a need for a container to hold food items such as popcorn and drinks close at hand. There is a need for a convenient container that may be used to hold items for the user, in some cases as a single use bag, supported by an upright surface close by to keep the items off the floor. The present invention aims to meet those needs.

Belgian Patent Application BE-A3-1013643 (Belde) describes a receptacle with means to mount the receptacle at the site of a hole to be drilled. The receptacle is not practical for mounting to a seatback. The receptacle has a through-hole in one of its panels to receive a drill bit. Although this receptacle could be mounted to a seatback by a spike protruding from the seatback, this is not practical because nobody wants to lean back in a chair against a spike protruding from the seatback.

Similarly U.S. Pat. No. 5,915,839 (Dennis) describes a bag for catching debris falling from a drill-bit as the bit drills through an upright surface. The document relates to a device outside the field of seat technology.

German Utility Model DE-U-20302093 (Merlaku) reveals a rubbish bag for aircraft passengers. The bag has a means to attach the bag to an upright seatback.

SUMMARY OF THE INVENTION

According to the present invention there is provided a portable collapsible container is removably mounted on an upright surface of a seatback, the container comprises: a front panel and a rear panel, each having an outer face and an inner face, an upper edge and a lower edge, and first and second side edges; and first and second collapsible sides, wherein the first side is attached to the first edges of the front and rear panels and the second side is attached to the second edges of the front and rear panels, the collapsible sides each comprise a preformed fold having an axis of bending aligned substantially parallel to the first and second edges; a collapsible base is joined to the lower edge of the front and rear panel; the base comprises a preformed fold having an axis of bending aligned substantially parallel to the lower edge; wherein the panels and base define an interior space by adjustment of the panels and preformed folds from a first closed position, where the panels are substantially adjacent and parallel, to a second open position, where the panels are separated and substantially parallel providing an internal volume; and a temporary mounting means configured to both mount the container to the upright surface and provide vertical and horizontal support to the container.

In places where people sit in seats arranged in rows, the people look over the seatbacks of the chairs in the row in front of them. There is a small space between the seats in which the people are sitting and the seatbacks for seats in front of them. The collapsible container is attachable to the seatback in front of a person sitting in a seat. Advantageously the sitting person can attach the collapsible container to the seatback in front of them. The sitting person can then store items in the collapsible container. A person sitting in a seat in a cinema can place their popcorn and hand carry items in the container. Advantageously they can see the container in front of them which helps remind them not to leave their hand carry items in the cinema. The sitting person does not have to leave their hand carry items on the floor where they might lose it in the dark cinema. The person does not have to leave their popcorn on the floor where it might be kicked over.

Other people walk to their seats along the aisle between sitting people and the seatbacks in front of the sitting people. The collapsible container collapses to first closed position where the panels are substantially adjacent and parallel. In the closed position the panels are nearly flush with the upright surface of the seatback.

Advantageously the aisle is clear for people walking to their seat because the collapsible container does not intrude into the aisle when in the closed position.

In some embodiments means is provided to maintain the container in the first or second positions, or both, for example biasing in the sides.

By biasing the collapsible sides to maintain the container in the second open position the container is conveniently held open for a person to place their hand carry items into the container.

Alternatively by biasing the collapsible sides to maintain the container in the first closed position, the container panels remain flush against the upright seatback unless there is an item being stored inside the container which holds the container open. Advantageously the aisle is kept clear of protruding containers so that people can easily walk to their seat.

Preferably the container comprises closure means to hold the container closed, or in the first position, with the front and rear panels proximal to one another when the container is not in use. Advantageously the container does not fall open and block the aisle when people brush the container as they walk along the aisle.

In some embodiments the closure means comprises a magnetic means such that the front and the rear panels are held together magnetically. In this way the user may open the container by pulling the front panel away from the rear panel to overcome the magnetic attractive force and the container will close when the front panel is moved back towards the rear panel. In some embodiments a magnetic element is provided on the front panel and an attracting magnetic element is provided on the rear panel. In some embodiments the magnetic element are in the form of a strip provided at one or more edges of the front and the rear panels. In use the rear panel is placed directly against the upright seatback.

An advantage of providing the magnetic closure element in the rear panel is that it both serves as the temporary mounting means to mount the collapsible container to an iron upright seat back and also serves as a closure means which biases the collapsible container to the first closed position. The side walls may be flexible with neutral bias and the collapsible container will still be biased to the first closed position by the magnet. Hence lower cost side walls made from a flexible sheet is an option.

Another advantage of a magnetic closure is that it makes no sound as the collapsible container is opened or closed which makes the collapsible container ideal for use in concert halls.

In some embodiments the closure means comprises a clip usable to hold the front and rear panels adjacent to one another. Advantageously a clip can be felt in the darks, such as in a dark cinema. Thus a clip is ideal for securing the collapsible container in the closed position in cinemas.

In some embodiments the closure means may be a single use closure means that holds the container together before a first use, for example a tear-off closure strip that is removable by a user. Preferably before the closure strip is removed no contaminant can enter the interior of the collapsible container. So advantageously when the closure strip is removed, the container is ideal for holding food inside.

By an upright surface is meant a surface having a vertical component of orientation, such as a substantially vertical surface or a surface inclined at an angle of greater than 45 degrees to the horizontal. The application of the container is not limited to such surfaces. It is particularly adapted for use when attached to such surfaces. By collapsible is meant that a dimension of a panel or the size and capacity of the container may be changed by moving a first part of the panel or container relative to another. By attached to an edge of a panel is meant attached at the edge itself or attached to the panel adjacent to the edge.

Advantageously the collapsible container is attachable to the back of a seatback of a chair. The back of the seatback has a surface which is substantially vertical. A person sitting is a seat behind the seatback attaches the collapsible container to the seatback in front of them. Then the person can use the collapsible container to store their goods. The person does not have to leave their goods on the floor.

In some embodiments the sides are adapted to bend inwards in direction substantially parallel to the first and second side edges. The axis of bending is substantially parallel to the side edges. The sides bend inwards into the volume between the front panel and rear panel as the container is collapsed. Collapsing the container does not extend the sides past the side edges. Advantageously as the container is collapsed it remains fully behind the seatback to which it is attached. It does not protrude into the space behind adjacent seatbacks as other people may be sitting in seats behind the adjacent seatbacks.

In some embodiments the sides each have a plurality of pre-formed folds aligned substantially parallel to the first and second side edges. The axis of bending of the folds is substantially parallel to the side edges. The sides are thereby divided along a plurality of fold axes. The distance between each fold being the furthest the portion of the side between folds extends into the volume between the front panel and the rear panel as the container is collapsed. The folds divide the sides so that the distance the sides extend into the volume between front and rear panels is limited. Advantageously this leaves more room in the volume inside the container to store items when the container is partially closed.

In some embodiments the base is attached to the front and the rear panels at their lower edges. The base is located at the opposite end of the collapsible container to the end of the collapsible container that opens. In use the base forms the bottom of the collapsible container. Item placed inside the container rest on the base.

Advantageously by placing attaching the base to the front and rear panels at their lower edges the volume inside the container between the panels is maximized for storing items inside the container. Furthermore by attaching the base to the rear panel, weight of items held in the container is transferred to the rear panel. Where the temporary mounting means is attached to the rear panel, the weight of the items held inside the container is efficiently transferred to the seatback upright surface two which the collapsible container is attached. Advantageously the collapsible container is thus made strong and reliable without over-thickening other portions of the collapsible container.

In some embodiments the base is attached to the lower edges of the sides. The weight of items supported on the base is thereby transferred to the sides. The sides hold the base preventing the base tear away from the panels. Preferably there is no gap between the base and lower edge of the sides because the base is connected along the entire length of the sides. Since there is no gap for items in the collapsible container to fall thru, the items are storable in the collapsible container without risk of them falling through the bottom of the container. Advantageously where popcorn is placed in the container it does fall onto the floor of the cinema. So there is less time and expense that has to be devoted to cleaning the cinema.

Preferably the sides, panels, and base are continuous and the base is contiguously connected to the panels and sides. Thus the container has no holes or gaps so that items stored in container cannot fall out. Preferably the base, panels, and sides are made of material impervious to liquids. Advantageously a liquid held in the container, such as butter on popcorn, does not drip through the container. Advantageously a floor below the collapsible container kept clean of items stored in the container.

In some embodiments the sides and the base are formed from separate components. Preferably the base is made from a material that is not punctured by an edge of any item stored inside. The base is not seen in use, so no expense need be made to select a material for the base for visual appearance. Preferably the sides are made from a material that may accept ink or dye for a printed image as the sides are visible in use.

In some embodiments the sides and the base are formed from a common component. Preferably the panels, sides and base are formed from a common component. Preferably an outline of the sides and base together is marked on an area of textile cloth, or paper sheet, or cardboard sheet, or preferably an outline of the panels, sides, and base are is marked on the cloth, paper, or cardboard. The outline of the sides and base is then cut or stamped from the cloth or paper so as to form the sides and base of the collapsible container as a single common component.

Advantageously the collapsible container is made efficiently. In some embodiments the base comprises one or more pre-formed folds aligned substantially parallel to the lower edges of the front and rear panels. The axis of bending is substantially parallel to the lower edge of the front and rear panels. The axis of bending is substantially perpendicular to the first and second sides. The folds of the base bend inwards into the volume between the front panel and rear panel as the container is collapsed. Collapsing the container does not extend the sides past the lower edges of the panels. As the container is collapsed the base collapses along axes of bending. The base collapses the between the front and rear panels. The base collapses into the volume between the front and rear panels and between the sides. The front and rear panels collapse together, and the base folds between them. Advantageously in use the collapsible container in the first closed position is collapsed and is substantially flush against the upright surface of a seatback so that cinema patrons can walk along the aisle between rows of seats without the collapsible container obstructing the aisle. Advantageously in us collapsible container in the second open position has a base with an area on which items inside the container can rest. Advantageously the maximum volume between panels is achievable because the panels remain substantially parallel when the container is in the open position.
